DEVICE FOR DISPENSING CHEMICAL SPECIES ON SURFACES

摘要

The present invention relates to a device for dispensing chemical species onto substrates for use in generating a biological and/or biochemical assay plate for detecting the presence of mobile target reactants that bind to probe reactants immobilized on said assay plate, said device comprising a chamber for holding said liquid species, a channel having a first end communicating with said chamber and a second end through which said chemical species is delivered when said device is brought into contact with said substrates and a wire being located in the channel. The object to provide a device for dispensing chemical species onto substrates that is easier to handle and has a more reliable operation than devices according to the state of the art is solved according to the present invention by a device where said wire is connected with a drop weight.
